Abstract

This paper describes how to compute inductance and resistance of any simple loop located near a conductive plane. The software used, InCa, has been presented in earlier papers. The image method is first used to take the ground plane into account. This modeling assumes infinite ground plane dimensions and conductivity. Results are compared to those 3D finite element software using specific shell elements. Effect of a finite conductivity is then analysed, using this 3D finite element tool with an impedance boundary condition. Finally, the ground plane is considered as a closed loop of finite dimensions and conductivity. Results are compared to measurements and the geometrical ground plane characteristics influence on loop inductance is studied
